Maitiro Ekuvhiya | "Maitiro eKirschner Wire Tension Band" ekugadzirisa mukati memuviri pakurapa Bennett's Thread

Kutyoka kwaBennett kunokonzera 1.4% yekutyoka kwemaoko. Kusiyana nekutyoka kwakajairika kwehwaro hwemapfupa emetacarpal, kusuduruka kwekutyoka kwaBennett kwakasiyana zvikuru. Chidimbu chepamusoro cheproximal articular chinochengetwa munzvimbo yacho yekutanga nekuda kwekudhonzwa kwe oblique metacarpal ligament, nepo chidimbu che distal, nekuda kwekudhonzwa kwe abductor pollicis longus uye adductor pollicis tendons, chinotyoka dorsoradially uye supinates.

Kune vanhu vakakuvara Bennett, kurapwa kwekuvhiya kunowanzo kurudzirwa kudzivirira kukanganisa kubatana kwejoini recarpometacarpal nechigunwe. Panyaya yekurapa kwekuvhiya, masisitimu ekugadzirisa maplate nescrew, pamwe neKirschner wire internal fixation, anoshandiswa zvakanyanya mukurapa. Nyanzvi dzepaChipatara chechitatu cheHebei dzakapa zano rekuti Kirschner wire tension band ishandiswe, iyo inosanganisira kuchekwa kudiki kusingapindike kugadzirisa kutyoka kwaBennett, zvichiita kuti pave nemigumisiro yakanaka.

Danho 1: Gadzira chidimbu che 1.3 cm parutivi rwe radial rwe carpometacarpal joint, cheka chidimbu nechidimbu kuti nzvimbo yacho ionekwe, dzosera abductor pollicis longus kudivi re ulnar, uye ratidza divi re dorsal re carpometacarpal joint.

Danho rechipiri: Isa tambo yeKirschner nemaoko woiburitsa neruoko kuti uderedze kutsemuka. Isa waya yeKirschner ye1 mm nepamucheto wekutsemuka kwedivi, 1-1.5 cm kubva pajoini recarpometacarpal, kuti ugadzire chidimbu chepfupa cheproximal. Mushure mekunge waya yeKirschner yapinda muchidimbu chepfupa, ramba uchiifambisa ne1 cm.

Danho rechitatu: Tora waya woitenderedza nemufananidzo wechisere kumativi ese ewaya yeKirschner, wobva waisunga panzvimbo yayo.

Nzira yeKirschner wire tension band yakashandiswa pakutyoka kwakawanda, asi pakutyoka kwaBennett, kuchekwa kudiki kunowanzoita kuti kusaonekwe zvakanaka uye kunoita kuti maitiro acho ave akaoma. Pamusoro pezvo, kana kutyoka kwacho kukabviswa, waya imwe chete yeKirschner ingasanyatsogadzirisa chidimbu chepfupa reproximal. Kushanda kwayo muchipatara kunogona kunge kushoma. Kunze kwenzira yekubatanidza tension band yataurwa pamusoro apa, kunewo Kirschner wire fixation yakabatanidzwa ne tension band technique, iyo yakataurwawo mumabhuku.
